Forms

proportiono, proportionare, proportionavi, proportionatum; first conjugation; also spelled proporciono.[1]

Etymology

It is from Latin proportiō (“proportion”).[1][2] The TLL rejects a participle proportiōnātus that older dictionaries cited from an interpolated early edition of Firmicus Maternus.[3]

Earliest recorded meaning

It is a medieval word.[2] Among the DMLBS's oldest records is Adelard of Bath's translation of Euclid's Elements, where quantities are proportioned to another quantity.[2]

Semantic evolution

It was used of number, size and amount, and figuratively of degree, as of penalties proportioned to an offence;[2] in scholastic philosophy things were said to be proportioned to one another, and in the passive it meant to be in proportion with something.[1] In Polish documents of the 15th century it also meant to adapt or fit, as of preachers suiting their words to their hearers.[1]
